Oracle VM VirtualBox: Ticket #8512: Host-Only Network Problems After Upgradehttps://www.virtualbox.org/ticket/8512
<p>
Host: Windows-7 64-bit
Guest: Oracle Linux
</p>
<p>
I configured 2 network interfaces to my guest: NAT and Host-Only using <a class="wiki" href="https://www.virtualbox.org/wiki/VirtualBox">VirtualBox</a> 4.0. The Host-Only has a static IP for both the Host (192.168.56.1) and the Guest (192.168.56.101).
</p>
<p>
It worked like a charm.
</p>
<p>
Then I Upgraded from VB 4.0 to 4.0.4.
</p>
<p>
My network set-up before upgrading had a Host-Only adapter with IP=192.168.56.1 and Mask=255.255.255.0. After upgrading this changed to IP=169.254.208.136 and Mask=255.255.0.0.
</p>
<p>
I tried to change the Host-Only settings back the pre-upgrade values via File-&gt;Preferences-&gt;Network. It appears to work. It popped-up the security warning which I ok'ed. But it didn't REALLY change the IP config. The Windows "ipconfig" command displays the wrong IP and Mask. Pinging my guest also fails with "Destination host unreachable"
</p>
<p>
Then I started <a class="wiki" href="https://www.virtualbox.org/wiki/VirtualBox">VirtualBox</a> running "as Administrator" and tried to change the Host-Only IP configuration via File-&gt;Preferences-&gt;Network. This time it also appeared to work, but the Windows "ipconfig" command displays the wrong IP and Mask. Pinging my guest also fails with "Destination host unreachable".
</p>
<p>
So I do not believe that this is a Windows Security problem.
</p>
<p>
Each time restart Virtual Box and check the IP settings in File-&gt;Preferences-&gt;Network, I see that the Host-Only configuration reverted back to the wrong IP and Mask!
